Prediction of delivery among women with early preterm labor by means of clinical characteristics alone

OBJECTIVE: This study was undertaken to assess whether individual clinical factors or combinations thereof could be used to accurately predict the risk of delivery within 1 week of admission among women with preterm labor and minimal cervical dilatation. STUDY DESIGN: We performed a case-control study of patients admitted to our institution with preterm labor and minimal cervical dilatation. A case patient was a patient who sought treatment with uterine contractions between 24 and 34 weeks' gestation with cervical dilatation 70 potential predictors was recorded. Statistical analysis consisted of bivariate and multivariable methods. We also generated a multivariable clinical predictive model with the purpose of detecting a proportion as high as possible of those destined to be delivered within 1 week (high sensitivity). We estimated that we would need 50 case patients and 150 control subjects to detect an odds ratio of 2.5 for risk factors with a prevalence of 20%, an alpha error of.05, a beta error of.20, and a control subject/case patient ratio of 3:1. RESULTS: Three variables were eligible for inclusion in our logistic models according to the bivariate analyses-bleeding on admission, substance abuse, and admission white blood cell count >/=14,000 cells/microL. The simplest and most favorable model included only 2 variables, bleeding and substance abuse, and yielded a sensitivity of 46% and a specificity of 76%. The full 3-variable model had similar test characteristics. For no model were we able to achieve a sensitivity >/=50%. CONCLUSION: The results of this case-control study suggest that combinations of clinical factors do not yield an adequate level of discrimination to be used alone for predicting the likelihood of delivery within 1 week among patients with minimal degrees of cervical dilatation.     

Eating disorders and reproduction

Eating disorders are common and characteristically affect young women at what would otherwise be their peak of reproductive functioning. Anorexia nervosa and bulimia nervosa impinge on reproduction both behaviourally and physiologically, with effects on menstruation, ovarian function, fertility, sexuality and pregnancy. This review presents a summary of current knowledge and makes suggestions for future research, along with some clinical recommendations for the management of eating disorders in pregnancy.     

FLUDAP: salvage chemotherapy for relapsed/refractory aggressive non-Hodgkin's lymphoma

The aim of this study was to investigate the combination of fludarabine phosphate, dexamethasone, cytosine arabinoside and cis-platinum (FLUDAP) in the treatment of patients with relapsed/refractory aggressive non-Hodgkin's lymphoma (NHL). This regimen comprises: dexamethasone 100 mg/d continuous infusion (cont. inf.) d1-3; cytosine arabinoside (ara-C) 1 g/m2/d cont. inf. d 2,3; fludarabine phosphate 30 mg/m2 short inf. 4hr prior to each 24hr ara-C inf.; cis-platinum 50 mg/m2 4hr inf. at the start of each 24hr ara-C inf. G-CSF (lenograstim, Granocyte) is given at 263 microg s.c. daily from day 7 until the neutrophil count reaches 1.0x10(9)/l. The regimen repeats at 21 day intervals. A total of 33 patients were registered (median age 47 years; 24 males, 9 females); the majority (73%) were refractory to their previous treatment and most had advanced disease by Ann Arbor stage. Thirteen (39%) of the 33 enrolled patients (52% of the 25 fully evaluable patients who received at least 2 courses of FLUDAP) responded to treatment. A maximum response of complete remission was achieved in 5 patients, good partial remission in 3, and partial remission in 5. Twelve patients went on to successful stem cell supported intensification therapy. Median survival times were higher in the responding patients, and in those patients transplanted post-FLUDAP. The toxicity associated with the FLUDAP regimen was generally predictable; frequently reported severe events included haematological toxicity and infection. In conclusion, the FLUDAP regimen shows promise as a salvage regimen and increases the available therapeutic options in the treatment of recurrent/refractory aggressive NHL.     

Pilot study of dermal and subcutaneous fat structures by MRI in individuals who differ in gender, BMI, and cellulite grading

BACKGROUND/AIMS: Puckered, dimply skin on the thighs, hips, and buttocks is known as cellulite. The cause of cellulite is not known, although there are a number of different hypotheses. In this study, we use magnetic resonance (MR) micro-imaging to study cellulite skin. To the best of our knowledge, this is the first reported MR study of cellulite. METHODS: High-resolution in vivo MR images of the postlateral thigh skin of two male groups and four female groups were obtained. Subjects were grouped according to their body mass index (BMI) and cellulite grade. A qualitative assessment of how MRI can be used to differentiate skin tissue at different levels of cellulite grading was performed. RESULTS: We found that changes in skin architecture with cellulite can be visualized by in vivo MR micro-imaging. The skin fat layers beneath the dermis and down to the level of muscles are well visualized in the images. Also, the diffuse pattern of extrusion of underlying adipose tissue into dermis is clearly imaged, and was found to correlate with cellulite grading. We also show that other skin tissue parameters such as (a) the percentile of adipose vs. connective tissue in a given volume of hypodermis and (b) the percentile of hypodermic invaginations inside the dermis are correlated with cellulite grade. CONCLUSION: MR images can be interpreted to measure tissue parameters correlated with cellulite. Considering that we had only three subjects in each group, the achievements of this pilot study were highly satisfactory. We have shown that the in vivo micro-MR is a technique able to detect the effects of cellulite and gender. This study can be extended for further investigations of drugs and/or medical devices for cellulite treatment.     

Radial keratotomy: a review of 300 cases.

Three hundred consecutive cases of radial keratotomy performed between 1985 and 1990 were reviewed. There were no sight threatening complications of surgery and no patient lost one or more lines of corrected Snellen acuity. Overall 78.7% saw 6/12 or better unaided postoperatively and 51.7% saw 6/6 or better. Refraction showed 61.3% to be within 1 dioptre of emmetropia and 86.7% were within 2 dioptres. Further analysis demonstrated that results of unaided acuity and proximity to emmetropia were much better for low (< -2.87 D) and moderate (-3.0 to -5.87 D) than for high (> -6.0 D) myopes.     

Modified Z-plasty repair of webbed neck deformity seen in Turner and Klippel-Feil syndrome.

OBJECTIVE: Webbed neck deformity exists in many syndromes including Turner's or Klippel-Feil syndrome. Multiple problems are encountered with existing techniques to correct a webbed neck deformity. In Turner's syndrome, a subcutaneous band of thickened fascia and a low neck hairline present a challenge to the surgeon when designing a repair. The authors propose the following new technique that addresses both issues. MATERIAL AND METHODS: Five patients with webbed neck underwent this new procedure. A Z-plasty is performed with the midline arm down the length of the web. The subcutaneous fibrous band is excised, the shortened trapezius is released, and the hair-bearing flap is excised. The anterior flap is rotated and advanced to join its mate flap from the contralateral neck at the posterior midline. A resultant dog-ear near the acromion is corrected with an additional Z-plasty. RESULTS: In all five patients, the functional and aesthetic results were very satisfactory to both patient and surgeon. An 11-year follow-up is presented with excellent correction of the webbing. Both limited range of motion and the cosmetic deformity are addressed by this technique. CONCLUSION: The results obtained by using the simplified modified Z-plasty technique for repair of webbed neck deformity are very satisfactory. We propose the use of this technique for correction of webbed neck deformities whenever the posterior surface of the neck web contains a significant amount of hair.     

Pseudophakic retinal detachments. Anatomic and visual results.

Retinal reattachment rates and visual results were analyzed in 227 consecutive primary pseudophakic rhegmatogenous retinal detachments. The overall anatomic reattachment rate was 90%, with no significant difference between the anterior chamber (AC) and posterior chamber intraocular lens groups. Visual results were significantly worse in the AC lens group (P less than 0.05). Negative prognostic indicators for reattachment included age greater than 65 years, poorer preoperative vision, larger extent of the retinal detachment, inability to identify a retinal break, longer duration of symptoms before presentation, and grades C or D proliferative vitreoretinopathy (P less than 0.05). In addition to the above factors, eyes with AC reaction, AC lenses, and macular detachment had a poorer visual prognosis.     

The completeness of AIDS case reporting, 1988: a multisite collaborative surveillance project.

OBJECTIVES. The purpose of this study was to evaluate the completeness of acquired immunodeficiency syndrome (AIDS) case reporting. METHODS. Statewide or hospital-specific 1988 medical records were linked with AIDS surveillance in six sites. Medical records were reviewed for persons who had diagnoses suggesting human immunodeficiency virus (HIV) infection or AIDS but were not reported to AIDS surveillance by September 1989. RESULTS. Among 4500 hospitalized persons diagnosed with AIDS through 1988 in the six sites, completeness of reporting was 92% (95% CI = 89%, 96%; range across sites = 89% to 97%). Completeness of reporting was high in males (92%), females (95%), Whites (95%), Blacks (90%), Hispanics (92%), men reporting sexual contact with men (92%), persons reporting injecting-drug use (91%), and persons exposed to HIV through heterosexual contact (99%). In Medicaid enrollees (two states), completeness of reporting was 99% (95% CI = 95%, 99%) in inpatients and 90% (95% CI = 79%, 90%) in outpatients. Of previously reported persons with AIDS, 82% were reported within 5 months of diagnosis. CONCLUSIONS. Completeness of AIDS reporting was high, overall and in each major demographic and HIV exposure group. These results demonstrate that current surveillance data in these six sites provide timely and accurate information regarding persons with AIDS.
